MAX17606AZT+T is a highly efficient, low-cost power management integrated circuit (PMIC) designed to provide optimized power solution for portable and mobile applications. Specifically, the MAX17606AZT+T is a versatile power management application-specific integrated circuit (PMIC) for high performance and noise sensitive applications. Its features include three-phase buck converter with local inductor optimization and adjustable slew rate, an adjustable charge pump with selectable current and voltage limits, a fully integrated and programmable linear regulator, and a host of other features that make it an ideal choice for a wide range of applications.

The charge pump in the MAX17606AZT+T provides up to 6 Amps (max) output current and 10V (max) output voltage, allowing designers to power high-density memory, such as NAND and NOR flash. The adjustable slew rate of the buck converter allows designers to optimize the converter performance and efficiency of the design. The adjustable current limit allows designers to reduce the total output current, enabling increased power savings.

The fully integrated linear regulator in the MAX17606AZT+T provides excellent current regulation, low noise operation, and fast transient response. The linear regulator is programmable and has two power modes: one mode can be selected to provide a fixed output voltage, while the other mode can be used to configure the linear regulator to track changes in the supply voltage, allowing for dynamic power savings.

The MAX17606AZT+T has a wide input voltage range from 4.5V to 30V and can be used to drive DC motors and other low voltage applications. It includes many features for protecting the system against faults, such as over-voltage, under-voltage, over-temperature and short-circuit protection. The MAX17606AZT+T is also drop-in compatible with most other popular multi-power PMICs, allowing for easy migration across platforms.

The MAX17606AZT+T is well-suited for use in portable and mobile device applications, such as mobile phones, personal digital assistants, digital cameras, portable audio players, cordless phones, and other battery powered equipment. It is also suitable for many other applications such as industrial and automotive instrumentation, power management in small to medium embedded systems, and point-of-load (POL) power supply applications.

The working principle of the MAX17606AZT+T is based on the optimized power-supply architecture, which involves three main components: the buck converter, the linear regulator, and the charge pump. The buck converter is the main power switching element, which steps the input voltage down to the required output voltage for the particular application. The charge pump is used to convert the input voltage to a higher level, allowing for higher current drive capability, while the linear regulator provides the final voltage output and current regulation.

The buck converter is designed to provide the highest efficiency in a low-voltage, low-power system. It consists of an inductor and a field-effect-transistor (FET). The FET is used to switch the output voltage of the inductor and the current flowing through it is optimized to achieve the highest efficiency. Both the current and the output voltage of the inductor are adjustable for different applications.

The linear regulator is used to provide a flat and stable voltage output. It consists of a comparator and an output amplifier, which works together to regulate the output voltage. The output amplifier senses the error voltage between the output voltage and the reference voltage and is used to adjust the current supplied to the output. The linear regulator provides fast transient response, low output noise, and excellent voltage regulation.

The charge pump is used to provide current and voltage drive capability to the output. It consists of four capacitors and a current limiting resistor. The capacitors store the energy and when connected to the output, the stored energy is converted into the output voltage. The current limiting resistor limits the amount of current drawn from the output, thus providing the required voltage and current drive capability.

In conclusion, the MAX17606AZT+T is a highly efficient, low-cost power management integrated circuit (PMIC) designed to provide optimized power solution for portable and mobile applications. It provides three-phase buck converter with local inductor optimization, adjustable charge pump with selectable current and voltage limits, and a fully integrated linear regulator. With its wide input voltage range from 4.5V to 30V, the MAX17606AZT+T is well-suited for use in a wide range of applications, including portable and mobile devices, industrial and automotive instrumentation, power management in small to medium embedded systems, and point-of-load (POL) power supply applications.
